Aluminium carbide on hydrolysis produces

Options

A. Acetylene gas
B. Methane gas
C. Carbon dioxide gas
D. All of the above

Explanation

To determine the products of the hydrolysis of aluminum carbide (Al4C3), we can follow these steps:

### Step 1: Write the formula for aluminum carbide
The chemical formula for aluminum carbide is Al4C3.

### Step 2: Understand hydrolysis
Hydrolysis is a chemical reaction involving water. In this case, aluminum carbide reacts with water (H2O).

### Step 3: Identify the products
Upon hydrolysis, aluminum carbide produces two main products:
1. Aluminum hydroxide (Al(OH)3)
2. Methane gas (CH4)

### Step 4: Write the balanced chemical equation
To balance the reaction, we need to ensure that the number of atoms for each element is equal on both sides of the equation. The unbalanced reaction can be written as:
\[ \text{Al}_4\text{C}_3 + \text{H}_2\text{O} \rightarrow \text{Al(OH)}_3 + \text{CH}_4 \]

Now, let's balance it step by step:
- Aluminum: There are 4 Al atoms in Al4C3, so we need 4 Al(OH)3 on the product side.
- Carbon: There are 3 C atoms in Al4C3, so we need 3 CH4 on the product side.
- Oxygen: Each Al(OH)3 has 3 OH groups, so 4 Al(OH)3 will have 12 OH groups, which means we need 12 water molecules to provide the necessary oxygen.

The balanced equation becomes:
\[ \text{Al}_4\text{C}_3 + 12 \text{H}_2\text{O} \rightarrow 4 \text{Al(OH)}_3 + 3 \text{CH}_4 \]

### Step 5: Conclusion
Thus, the products of the hydrolysis of aluminum carbide are aluminum hydroxide and methane gas.

### Final Answer
Aluminum carbide on hydrolysis produces aluminum hydroxide and methane gas.
